Non-comic appearances. Cinnamon and other Shotgun Shuffle characters seem to occasionally post in the comments of various comics. It's unknown who the posters are and it is doubtful that these appearances are considered canon but it adds a level of fun to the overall Shotgun Shuffle experience. Cinnamon's first post in the comments of the comic can be found here and she's posted periodically ever since.
